A TTORIVEY WILL E. HATHEWAY, 0F BRIDGOB'I, CONNECTICUT.

To all whom it may concern:

Be it known that I, WILLIAM E. Ha'r m- WAY, citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certam new and useful Improvements in Chair- Tips; and I do hereby declare the following to be a full, clear, and exact descriptlon of the invention, ,such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvement in chair tips.

The object of my invention is to so construct the tip that the retaining points are located far enough within the cup-shaped tip to get a firm hold in the end 0 a chair leg and far enough from the edge to avoid splitting. To do this, and also leave a smooth bearing surface for-the tip, I have made the device in two parts, viz.: The cup is first formed from a single piece of metal with a central rivet stud integral with'the cup and riveting or heading over this stud on to a point holding plate.

Referring to the drawings wherein the same figures of reference indicate like parts throughout the several views: Figure 1 represents an inside plan view of the completed tip; Fig. 2 indicates a side elevation of the completed'tip; Fig. 3 is a central sectional view on line 3, 3 of Fig. 1; Fig. 4 is a central sectional view. of the cup and rivet stud; and Fig. 5 is a plan view of the central plate having holding points said points not having yet been turned up.

The first operation consists in forming the cup 1 by upsetting the end of a roundpiece of wire practically the size of the stud 2,

andmaking said stud an integral part of. the cup, thus leaving. the outer curved part of the cup, in contact with the floor, perfectly smooth. This stud: provides the attaching means for the plate 3, having the central into integral therewith,

hole 4 adapted to embrace the stud 2 as shown in Fig. 3. The retaining points 5 are an integral part of the plate and are bent an upright position before the plate is secured to the cup.

I am aware that'cup-shaped tips have previously been made, but so far as known the retaimng points form an integral part of the cup and'are'located at the perimeter thereof. The objection to such a construction is that it brings said retaining points too close to the edge of the chair legs to alwa s-insure a firm hold in the wood, while in my improved construction the retaining-points, as before mentioned, are located well within the chair leg where a firm hold is always insured. The novel manner of attaching the retaining points to the interior of the cup without the aid of screws, rivets or similar means of attachment that would require piercing the bottom of the cup and thus present a rough surface to a polished fioor is entirely avoided.

Having thus described my invention, what I claim is A chair tip comprising a cup having a rounded bottom and a circular upturned flange, the edge of which is in one plane for engaging the bottom of the chair leg, a central projection within the cup and integral therewith, a retaining plate having a central opening to embrace said central projection and secured thereto by heading over said projection against the retaining plate, said plate and projection located entirely below the edge of the cup so as not to interfere with said edge resting against the bottom of the chair leg.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM E. HATHEWAY.
